Influence of WO3 content on gamma rays attenuation characteristics of phosphate glasses at low energy range

Open Chemistry, 2023
The radiation attenuation characteristics of WO3-Li2O-ZnO-P2O5 glasses have been examined using Phy-X software. The linear attenuation coefficient is correspondingly increased with the inclusion of WO3, which indicates the existence of a reducing ...
